Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles (UAVs), and in particular relates to a method, system and application for reconnecting and re-online WiFi configuration of formation aircraft. Background Art

[0002] During formation aircraft flight performances, some aircraft were unable to connect to the ground station server immediately after being powered on. This resulted in an inability to complete overall control and a full-scale flight performance in a short period of time. The waiting process for restarting the aircraft was long, and operational needs were not met. Designing a solution to ensure that the Wi-Fi configuration of the fleet aircraft could be reconnected and put back online became a technical problem that needed to be solved.

[0003] Through the above analysis, the problems and defects of the existing technology are as follows: the existing technology relies on the disconnection and reconnection mechanism of the WiFi module itself. During the power-on period of the aircraft, if no WiFi is found or the IP address is not reasonably applied for, there will be a long waiting time, and the entire fleet of aircraft cannot be online. Some aircraft need to be repowered, which affects the efficiency of completing formation aircraft performances or performing other tasks. Summary of the Invention

[0004] To overcome the problems existing in the related art, the embodiments disclosed in the present invention provide a method, system and application for reconnecting and getting back online via Wi-Fi configuration of a formation of aircraft.

[0005] The technical solution is as follows: A method for reconnecting and re-online WiFi configuration of a formation aircraft includes:

[0006] The communication status of the wireless communication signal is obtained in stages, and based on the communication status, it is determined whether to restart the wireless communication module. The abnormal wireless communication signals of individual aircraft in the formation are adjusted so that the aircraft in the formation can be online as a whole within a certain period of time, and the real-time status information of the formation aircraft is transmitted back to the ground station.

[0007] In one embodiment, the method for reconnecting and re-online wifi configuration of the formation aircraft includes the following steps:

[0008] S1: After the aircraft is powered on, the application starts running to obtain the current Wi-Fi signal strength;

[0009] S2: If the Wi-Fi signal strength is sufficient, proceed to the next step; if the Wi-Fi signal strength is insufficient, and the cumulative duration exceeds 15s to 30s, preferably 15s, restart the Wi-Fi module driver;

[0010] S3: Get the Wi-Fi gateway. If the acquisition fails for more than 15s to 30s, preferably 15s, then restart the Wi-Fi driver. If the acquisition succeeds, proceed to the next step.

[0011] S4: Ping the default gateway. If more than 3 packets can be pinged, proceed to the next step. Otherwise, if the ping time exceeds 15s to 30s (preferably 15s), restart the driver.

[0012] S5: Ping the static URL of the ground station server. If the ping is successful, the network connection is considered normal and the signal is sent back to the ground station. Test again after 5 to 10 seconds. 5 seconds is preferred.

[0013] In one embodiment, in step S1, obtaining the current WiFi signal strength includes: obtaining system WiFi signal related information through the Linux system wpa_cli status command.

[0014] In one embodiment, in step S3 of obtaining the Wi-Fi gateway, the system Wi-Fi signal related information including gateway information and signal strength is obtained through the wpa_cli status command.

[0015] In one embodiment, pinging the default gateway in step S4 includes:

[0016] Under Linux, get the relevant information command: ping-c3-qAI wlan0;

[0018] In the present invention, ping is a command under Windows, Unix and Linux systems. Ping is also a communication protocol and is part of the TCP / IP protocol. The "ping" command can be used to check whether the network is connected, which can be very helpful in analyzing and determining network failures.

[0019] In one embodiment, the pinging in step S5 includes the following steps:

[0020] Command: ping 172.168.0.201;

[0021] The MCU responds to the message:

[0028] rtt min / avg / max / mdev=4.509 / 10.089 / 22.208 / 5.854ms.

[0029] Another object of the present invention is to provide a formation aircraft WiFi configuration reconnection and re-online system comprising:

[0030] The current signal strength acquisition module is used to obtain the current Wi-Fi signal strength after the aircraft is powered on and the application starts running;

[0031] The signal strength judgment module is used to proceed to the next step if the WiFi signal strength is sufficient; if the WiFi signal strength is insufficient and exceeds 15s to 30s, the WiFi module driver is restarted;

[0032] The gateway acquisition module is used to obtain the Wi-Fi gateway. If the acquisition fails for more than 15s to 30s, preferably 15s, the Wi-Fi driver will be restarted. If the acquisition succeeds, proceed to the next step.

[0033] The default gateway module is used to ping the default gateway. If more than 3 packets can be pinged, proceed to the next step; otherwise, the cumulative ping time exceeds 15s to 30s, preferably 15s, and the driver is restarted.

[0034] The static URL judgment module is used to ping the static URL of the ground station server. If it can be pinged, it is considered that the network connection is normal and the test will be carried out again after 5s to 10s.

[0035] Another object of the present invention is to provide an information data processing terminal, which includes a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes the method for reconnecting and re-online configuration of the formation aircraft WiFi.
